CHARLES G. GBOVER, OF NESGOPECK, PENNSYLVANIA.

To all whom it may concern: g V Be itknown that I, CHARLES G. GRovER, a Citizen of the United States, residing at Nescopeck, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Reamer, of which the following is a specification.

The device forming the subject matter of this application is a reamer, and one object of the present invention is to provide a reamer having a side cutter of novel form, novel means being provided for bowing the cutter outwardly. e 'Anotlierobject of the invention is to provide a reamer in which the body portion thereof may be reversed, so as to present new edges for cooperation with the operative edges of the side cutter.

It is within the scope of the invention to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

lVith the above and other objects in view which will appear as the description proceeds, the invention resides in the combina. tion andarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention, herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In theaccompanying drawing :Figure 1 shows the invention in side elevation; Fig.

2 is a side elevation, the view point in Fig. 2 being 90 degrees remote from the view point in F ig. 1; Fig. 3 is an elevation similar to F ig. l, the filler, however, having been removed and the side cutter being shown as lying fiat against the body portion of the reamer; Fig. l is a. cross section on the line l4 of Fig. 1; Fig. 5 is a longitudinal sectional detail showing the means I whereby the ends of the side cutter are assembled with the body of the reamer.

In carrying out the present invention there is provided a body 1 equipped at one end with a tang 2 and comprising a cylindrical portion 3, the body of the reamerbeing of rectangular cross section adjacent one end, as shown at 4. The side faces of the squared end portion 4 converge toward each other, so that the portion 4 of the body of the reamer is of tapered form. Referring enamels.

Specification of Letters Patent. Patented Dec. '7, 1915. Application filed September 8, 1914. Serial No. 860,744; I

to Fig. 4 it will be observed that this squared portion 4 of the body of the reameris 'pro- I vided with cutting edges (3, '7, 8 and 9.

, Extended longitudinally of the body l is a cutter 10 which in cross section is of plane-convex form and is provided with cutting edges 11 and Adjacent its ends the cutter 10 is equipped with longitudinal slots l i. Securing elements 15 pass through the slots '14: and enter suitable openings formed in the bodyportion of the reamer.

Screws 1.6 are threaded into openings '17 formed in the body 1 of the reamer and constitute means whereby the cutter 10 may be bowed outwardlv to any desired extent;

The cutter 10 is resilient and when not'en gaged bv the screws 16. lies against one side face of the body of the reamer, as clearly I shown in Fig. 3. i

Ifdesired, a filler may be interposed be- ,tweenthe outer ends of the screws 16 and the inner face of the cutter 10' The filler As will be understood readily, the cutter 10 may be bowed outwardly by manipulating the screws 16, thereby to regulate the taper of the hole and to adjust the amount of reaming. The filler 18-20 may be omitted if desired as Fig. 3 will clearly indicate.

\Vhen the reamer is rotated in the direction 01' the arrow A in Fig. 4, the edge 110i the cutter 10 and the edge 9 of the body por-,

tion of the reamer are operative. If, however, the reamer is rotated in the direction of the arrow B, the edges 12 and 8 are effective. Shouldthe edges 8 and 9, or either of them become dull, the body portion of the reamer may be rotated with respect to the cutter 10, under which circumstances, the dulled edges 8 and 9 will be replaced, respectively, by'the edges 6 and 7 The slots 141: permit the resilient cutter 10 to be bowed to the desired'extent, under the action of the screws 16.

The device herein disclosed is adapted to beemployed for, reaming bushings, bearings,

and under any and all-conditions of a like sort, which call fora close and accurate fit between aninner andan outer or circumscribing part.

sible to cause the other ofthe cutting edges to cooperate with the cutter. v j 4. A reamer including a body; a side cutter extended longitudinally of the body; connections-unitingthe ends of the cutter with the body, one of said connections being a slidable. connection; body carriedad- "'justable means engaging the intermediate portion of the cutter to effect an outward bowing of-the cutter, the .body havingcutting edges, one of which cooperates with the cutter, the body being reversible to cause. the other of the cutting edges to cooperate. with the cutter.

' 5. A reamer comprising a body; a transversely flexible side cutter extended longitudinally Qf'the body and provided adjacent its ends with openings, one of Which is elongated longitudinally of the body; securing F elements in the openings and engaging the body; and a screw disposed transversely of the body and threaded thereinto, the screw engaging the cutter intermediate the ends of the cutter. a

In testimony that I claim'the foregoing as my own, I have hereto affixed my signature 1n the presence of two witnesses.
